Child's opinion, verbatim: It's a really good kit. I haven't tested all of the features, but I think it's a very good kit. The only problem with it is that on the bottom of the energy meter where you charge the energy meter and connect the motor generator, it's very annoying and hard to snap the cable from the motor or battery box so it will generate enough power. This is specifically for the motor. The battery box will still generate power, but not as much\/as fast, I don't think, when it's not completely tightly snapped. The Energy Meter is also like another version of Mindstorms. Not as complicated, though. The Energy Meter is like a whole new brain. It stores the energy, it hooks up motors and it can sense energy from the motors. It's like the motors have rotation sensors, but it's actually an energy generator. And better yet, it can also be pluggged in to LEGO Mindstorms EV3 and NXT to be used as a sensor.","review_amount":"4","rating_original":"4.2","rating_converted":"84.00","author_name":null,"embed":null}]}
